I can see that it would be useful in a professional capacity where having 50,000 photos was part of the job. But I must ask, what do you do with those photos? Do you really cull through them and share them or use them again? 50,000 of them? It seems like you've made the case for the memory hole I was talking about.

Of course, any software always had edge cases and niche uses. My complaint primarily was that this seems to fall in the bucket of not-terribly-useful-whiz-bang-stuff that Apple (and, by all means, not only Apple) likes to include so they have something to do PR about. Animoji was definitely in this category and every FAANG company is guilty of this to some degree.

I cannot imagine that, if you surveyed 10,000 users, even one of them would list "on-device facial recognition" as a feature that they need or want from their phones.
